Abstract
Techniques for protecting data using two password asymmetric encryption based on time-constrained password-based partner tokens. To encrypt data, a first partner computing device receives a first partner token from a second computing device. The first partner computing device decrypts the first partner token to recover first public key data generated by the second partner computing device. The first partner computing device derives a cryptographic encryption key to encrypt the data based on the first public key data, and based on first private key data generated by the first partner computing device. The second computing device may decrypt the encrypted data based on a second partner token generated by the first partner computing device, using a cryptographic decryption key derived using second private key data generated by the second computing device and second public key data generated by the first computing device and embedded and encrypted in the second partner token.
